Exchanges are scared to death of anything that had an ICO or looks like a security. Privacy coins are also a target. You can thank the good off US or A for that. Washington needs to get off its fat overstuffed ass and make some clear rules for crypto in general and take the power away from the SEC, we do not belong under their control.
I get the first part about securities, but there are plenty of other privacy coins that haven't been delisted. Just look at Monero, Dash or ZCash. Hell even Coinbase has ZCash for sale for USD.
Maybe there is a conspiracy to knock off Cloak for some reason or another, but the reality is there isn't that much traction on GitHub which sometimes (not always) means there isn't much on the development front.
